I have personally, and along with 2 of friends have had the same problem with them. Why? I don't know but tons of people have been fine with them. I the stock bosch's back on and started running fine. I guess it's hit or miss from what I see with MSDs.

I recommend double and triple checking the connections, listen for a nice soild click. The short wires on these cars tend slide on without making a good connection, and cause small miss.

I've ran MSD wires a couple times in the past without issue. Currently using the red GMPP wires.

i'd make sure all the wires clicked on the plugs all the way. if that doesn't work, check the plugs themselves. i got the 8.5 super cond. wires, no problem at all.

indeed, they are a bitch to get to click on. you need to make sure the top part (coil pack part) clicks twice. many people have had misses due to the wires not being on all the way

Definately sounds like a wire or two not on all the way.
